It was a warrant issued by a Spanish court that Github legally had to comply with. So Github did the minimum it could do, which was to block the website within Spain.
First it says:
Después de que un juez decidiese bloquear sus direcciones web, obligando a sus gestores a migrar dominios y buscar nuevo alojamiento, ahora ha sido GitHub, el servicio propiedad de Microsoft desde junio de 2018, el que ha acabado por bloquear el acceso al repositorio que alojaba la web y la aplicación de la plataforma desde España.
but then:
Pese a que el servicio de 'software' libre estaba entre los objetivos de las autoridades por dar cobijo a la plataforma independentista, fuentes de Microsoft España han confirmado a Teknautas que ellos no han recibido ninguna petición por parte de las fuerzas y cuerpos de seguridad del Estado para cerrar los repositorios de Tsunami por lo que la decisión se ha tomado a nivel internacional.
I'm not sure exactly what legal obligation Github actually had.
edit: based on the responses below that just says that Microsoft Spain didn't receive a request, not that Microsoft global didn't receive one. And otherwise, where would the request that Github published have come from?!

But according to the second paragraph Microsoft Spain denied having received a takedown request for the Github repository from the Spanish security services. It also says that the takedown request must have been made on an international level, but I'm not sure what that could refer to.
